Abstract:
ABSTRACT Marine macroorganisms are a potential source for new bioactive substances. In many cases marine microorganisms—especially bacteria—associated with these macroorganisms are actually producing the bioactive substances. One often is not able to immediately isolate microorganisms from collected macroorganismic materials; we therefore evaluated different methods for storage of such material, e.g., on board research vessels. These methods were the following: storage of macerates in sintered glass beads and 5% trehalose at −20°C (SGT method); storage of sections in 5% dimethyl sulfoxide at −70°C (SD method); storage of macerates at −20°C using the commercial ROTI-STORE system (RS method); storage of macerates at −20°C in 50% glycerol (GC method); and storage of macerates covered by mineral oil at 4°C (MO method). The SGT and SD methods resulted in numbers of and especially diversity of recoverable bacteria that were higher than for the other methods. Data for the RS method indicated its potential usefulness, too. The MO method resulted in growth during storage, thereby enriching a few selected microorganisms; the GC method resulted in a survival and diversity of recovered bacteria that was too low.

Abstract:
We describe traces of macroorganisms in association with the body imprints of trace-producers from Ediacaran (Vendian) deposits of the southeastern White Sea region. They are interpreted as traces of locomotion and are not directly related to a food gathering. The complex remains belong to three species: Kimberella quadrata, Dickinsonia cf. menneri, and Tribrachidium heraldicum. They were found in three different burials. The traces have the form of narrow ridges or wide bands (grooves and linear depressions on natural imprints). In elongated Kimberella and Dickinsonia, the traces are stretched parallel to the longitudinal axis of the body and extend from its posterior end. In the case of the isometric Tribrachidium, the trace is directed away from the margin of the shield. A short length of the traces indicates that they were left by the organisms that were covered with the sediment just before their death. The traces overlaid the microbial mat with no clear signs of deformation under or around the traces. A trace substance, apparently, differed from the material of the bearing layers (i.e., a fine-grained sandstone or siltstone) and was not preserved on the imprints. This suggests that the traces were made with organic material, probably mucus, which was secreted by animals in a stressful situation. The mucus traced the movements of the organism before death. The discovered traces of locomotion are direct evidence of the ability of some Ediacaran macroorganisms to move independently.

Abstract:
Defensins are immune peptides - HDP (Host Defense Peptides) that present high activity against viruses, bacteria and fungi in mammals, including humans. They are an important element of natural resistance in macroorganisms, when microorganisms couldn’t developed this resistance during the evolution. Defensins in vertebrate macroorganisms, have direct and indirect impact on germs, including stimulating the synthesis of immune substances such as cytokines, chemokines and growth factors.

Abstract:
All kinds of micro- and macroorganisms live in the massifs of clay soils: plants living in (or on) clay soils are called pelitophytes (from the Greek πηλός - “clay” and phyton - “plant”), micro- and macroorganisms living in clays, or associated with clays, they are called pelitophiles (from the Greek πηλός - "clay" and φιλία - "love"), that is, "loving clays" or "prone to clays." The article analyzes these groups of organisms and describes their role in the formation of the properties of clay soils and ecological-geological systems.

Abstract:
The circulating water of the cooling systems of petrochemical enterprises has a number of special features: the temperature of cooling water is in the range of 14-28 °С all year round, the evaporation of water in cooling towers increases the concentration of dissolved salts. Inevitable ingress of hydrocarbons, dosing of corrosion inhibitors, scaling, reagents for dispersing and softening of the water creates favorable conditions for micro- and macroorganisms development. Existing standards stipulate that the number of viable bacterial cells in planktonic form should not exceed 10 cells/ml, the number of bacteria in the adhered form is not regulated, nevertheless these organisms in particular lead to biocorrosion. During the assessing of the biological degradation of water cycle equipment materials, it was studied the micro- and macroorganisms that populate the surface of steel samples 20. Studies of the effect of this bacteria on the corrosion of steel 20 showed that this whole complex of micro- and macroorganisms, releasing metabolites into the water, also indirectly affects the processes of corrosion, and when choosing protection methods, it is necessary to take into account not only the presence and types of bacteria, but also the entire local biocenosis.

Abstract:

The focus of this dissertation is the extension of the innate immune response in wound healing and non-wound healing contexts. I am interested in interactions at the interface between macroorganisms and microorganisms from marine/aqueous environments. This dissertation explored two aspects of the interactions: 1) the presence and function of macroorganism secretions and 2) the role of secretions in managing microfouling on macroorganism surfaces. Particularly of interest are how barriers are biochemically reinforced to mitigate microfouling and the potential consequences of a breach in those barriers. The innate immune response, an evolutionary conserved system in vertebrates and invertebrates, provides an evolutionary context for developing the hypotheses.

In this dissertation the biochemical composition and uses of crustacean secretions are explored for barnacles, fiddler crabs and blue crabs. Fluids of interest were secretions released during barnacle settlement and metamorphosis and those collected from living adult barnacles, fluids on fiddler crab sensory appendages including dactyl washings and buccal secretions, and fluids from blue crab egg masses. The biochemical composition was determined using a combination of fluorescent probes and confocal microscopy, proteomics, and enzyme-specific substrates with a spectrophotometer.

I demonstrated that self-wounding is inherent to the critical period of settlement and metamorphosis, in barnacles. Wounding occurs during cuticle expansion and organization and generates proteinaceous secretions, which function as a secondary mode of attachment that facilitates the transition to a sessile juvenile. I showed extensive proteomic evidence for components of all categories of the innate immune response, especially coagulation and pathogen defense during attachment and metamorphosis. This work provides insight into wound healing mechanisms that facilitate coagulation of proteinaceous material and expands the knowledge of potential glue curing mechanisms in barnacles.

In order to test macroorganism secretions in a non-wound healing context, I examined fluids sampled from body parts that macroorganisms must keep free of microorganisms. I showed that two types of decapod crustaceans can physically manage microorganisms on most parts of their body, but certain parts are particularly sensitive or difficult to clean mechanically. I examined sensory regions on the fiddler crab, including dactyls that are important for chemoreception and the buccal cavity that is used to remove microorganisms from sand particles, and blue crab egg mass fluids that protect egg masses from fouling through embryo development.

This dissertation explores organismal interactions across scales in size, space, and time. The findings from the barnacle work inform mechanisms of attachment and glue curing, both central to understanding bioadhesion. The work on fiddler crabs and blue crabs contributes to our understanding of chemoreception of feeding and reproductive behaviors.

The work presented here highlights how biological secretions from macroorganisms serve multifaceted roles. In cases of physical breaches of barriers, or wounding, secretions coagulate to obstruct loss of hemolymph and have antimicrobial capabilities to prevent infection by microorganisms. In non-wounding cases, secretions remove microorganisms from surfaces, whether that is on the body of the macroorganism or in the immediate environment.

Abstract:
Chapter 11 entitled “Some early landmark studies” revisits several seminal articles that paved the way for the field of eDNA research. It first evokes the paper that first coined the expression “environmental DNA” in the late 1980s. Then, it describes how eDNA was first exploited in the early 1990s to reveal an unsuspected microbial diversity that morphology- or cultivation-based methods had failed to reach. In the late 1990s, microbiologists began to explore in several pioneer papers the functional insight provided by “metagenomes” (i.e., the collective genomes found in eDNA samples). In the 2000s, eDNA analysis was finally extended to macroorganisms. Chapter 11 reports such a use in two very different contexts (i.e., the detection of a contemporary invasive species, the bullfrog, and the reconstruction of past plant and animal communities from sediment and permafrost samples).

Abstract:
Los suelos están constituidos con una diversidad de fauna (mega, macro y microorganismos), poco explorada y estudiada. Las lombrices de tierra (invertebrados y macroorganismos del suelo, cuyo ancho es > 2000 μm) y las bacterias (microorganismos que miden entre 0 5 y 5 m) que habitan en el suelo, establecen una relación mutualista (entre organismos de diferente morfología y tamaño), cuando estas últimas colonizan el tracto digestivo de las lombrices (Lavelle et al., 1995). Parece que la gran mayoría de los invertebrados del suelo no poseen enzimas para digerir directamente la celulosa, lignina, taninos y complejos húmicos, en cambio estas enzimas, en su mayoría están presentes en las bacterias.
